Over time I have used most anti fogging products. None with any great success. I had read some good reports about the Pinlock visor insert. Googling it found no bad reports, all said it simply worked. My Shoei comes Pinlock ready, thinking that must be a good recommendation I ordered one from Bikebiz in Sydney. Package arrived and there was the fine print: Not to be used at night as it let in less than 80% of light. Googled Pinlock night and there were many posts across a few forums. Most said there was some star burst effect from on coming head lights. A couple did not like it all. Most said one got used to it and it was no longer a distraction. There being no appreciable loss of vision.
So I inserted the Pinlock and left for work at 430 as usual. I do an hour each way to work, mostly in the dark in winter. I live on the north coast of NSW. Temp rarely below 10. Big storms at times.
There was no fogging, none, I repeat none. Even with the visor down when stopped. I did not notice any loss of vision. On coming head lights and street lights did have some star burst effect. I did not notice it after the second day. Oncoming high beam was still annoying but no more so than usual.
Ran into a big storm the other night. No need to crack the visor at lights or in traffic. Keep it tight all the time as directions suggest. I was able to up the pace a bit on the motorway because I could simply see better. Did not notice the oncoming traffic.
Directions mention the insert becoming saturated when subjected to long wet periods, and the need to dry it out. After an hour in heavy rain there was no difference. So I do not know how it would go over longer runs.
I am pleased, something which really works. $58 delivered is pricy but now I think it is money well spent. Will not deliver to PO boxes.
